Problem 29
Question
Find each sum without the use of a number line. $$-3.6+(-2.1)$$
Step-by-Step Solution
Verified Answer
The sum of -3.6 and -2.1 is -5.7
1Step 1: Identify the numbers
Identify the numbers you need to add together, which are \(-3.6\) and \(-2.1\)
2Step 2: Add the absolute values of the numbers
Add together the absolute values of the numbers, ignoring the negative signs for now. The absolute value of \(-3.6\) is \(3.6\), and the absolute value of \(-2.1\) is \(2.1\). So, simplify \(3.6+2.1\) to get \(5.7\)
3Step 3: Take into account the negative signs
Since both numbers are negative, the sum is also negative. Therefore, add a negative sign to the result from Step 2 to get the final answer.
